Advice on Game Plan b/f Switch update

I am working on a game plan prior to the switch, update, and trying to limit spoilers, at least detailed ones. Put the game away for a while but now I think I should be grinding Shills, and rewards points. I’m guessing I’ll have to reconfigure the store for any upgrades anyway, but I could upgrade any old, coolers and shelving. Based on the P.C. update what advice would you give switch players to plan ahead?
